Hepatic cholate clearance as assessed by HepQuant-SHUNT is predictive of clinical outcomes in individuals with Fontan circulation

Yuli Y. Kim, Daniel Ganger, Alexis Z. Tomlinson, Isabella Z. Farkas, Jack Rychik, Joanne Imperial, Michael P. McRae, Greg T. Everson, Maarouf A. Hoteit | International Journal of Cardiology Congenital Heart Disease

Fontan-associated liver disease [FALD] is universal in individuals with Fontan circulation [FC]. The dual cholate clearance test is a noninvasive, flow-dependent measure of liver function. We aim to explore the association between cholate clearance and clinical outcomes in this population. read more →

HepQuant DuO® Test Enhances Clinical Decision Making in Compensated Advanced Chronic Liver Disease

Kerry Whitaker, Joanne C. Imperial, Michael P. McRae, and Gregory T. Everson | Journal of Clinical Medicine | January 2026

The HepQuant DuO® test is a noninvasive, blood-based test that assesses global liver health by quantifying liver function and physiology. The test generates a disease severity index (DSI) for assessment of risk for portal hypertension and large esophageal varices (LEV) to aid in the upper endoscopy (EGD) decision, provides a definition of disease severity to aid in clinical management, and enables serial testing to monitor changes in liver health over time, either improvement or worsening. A DSI cutpoint 18.3 was defined in a U.S. multi-center trial in advanced chronic hepatitis C (HALT-C) and validated in a second U.S. multi-center trial where the majority of cases (52%) had MASLD/MASH (SHUNT-V). In addition, the latter validation study included all common etiologies of cACLD, and a high percentage of the study subjects were overweight, obese, elderly, and had diabetes. In several studies, DSI has shown favorable diagnostic performance compared to other noninvasive tests. Using real-world data, the analysis evaluated the impact of DSI 18.3 in the EGD decision and in modifying decision making in patients with cACLD. read more →

Cholate clearance: improving the assessment of liver health compared to current liver tests (LFTs)

James R. Burton, Jr., MD, Edward Mena, MD, Bhaktasharan Patel, MD | Gastro Hep Advances | November 2025

Current liver function tests (LFTs) either indicate late-stage disease or hepatobiliary injury but do not accurately measure liver function. True quantitative liver function tests, analogous to creatinine clearance for the kidneys, are needed for assessing liver health. read more →
